Do you mean you want to remove the surrounding selection boxes from the objects on the chart?
I would do this (let's say there is only one object named "MyObject"):
ObjectSet("MyObject", OBJPROP_TIMEFRAMES, -1); //this will hide the object on all timeframes
ObjectSet("MyObject", OBJPROP_TIMEFRAMES, 0); //this will show object on all timeframes again, without the selection box
Of course you can make a loop for all of your objects, and you also can set different timeframe parameters if needed.
